InfluxDB+cAdvisor+Grafana配置Docker监控

一、配置influxdb

docker run -d \
   -p 8083:8083 \
   -p 8086:8086 \
   --expose 8090 \
   --expose 8099 \
   --name influxsrv \
   tutum/influxdb
默认用户名：root, 默认密码：root

# 创建数据库
create database 'cadvisor'; 

# 创建用户
CREATE USER 'cadvisor' WITH PASSWORD 'cadvisor'

# 用户授权
grant all privileges on 'cadvisor' to 'cadvisor'

# 授予读写权限
grant WRITE on 'cadvisor' to 'cadvisor'
grant READ on 'cadvisor' to 'cadvisor'

二、cadvisor数据收集，在监控节点启动

# docker run   --volume=/:/rootfs:ro   --volume=/var/run:/var/run:rw   --volume=/sys:/sys:ro   --volume=/var/lib/docker/:/var/lib/docker:ro   --volume=/dev/disk/:/dev/disk:ro   --publish=9090:8080   --detach=true   --name=cadvisor   google/cadvisor:latest -storage_driver=influxdb -storage_driver_host=192.168.1.100:8086 -storage_driver_db=cadvisor -storage_driver_user=cadvisor -storage_driver_password=cadvisor

storage_driver=influxdb 指定存储驱动,使cadvisor将数据存储到数据库中，更多存储插件，请参考这里

-storage_driver_host=influxdb:8086 InfluxDB数据库的地址

-storage_driver_db=cadvisor 数据库名称

如果要指定用户名可以用-storage_driver_user参数，默认是root

如果要指定密码可以用-storage_driver_password参数，默认是root  

  报错：
  W0130 03:47:13.734200       1 manager.go:313] Could not configure a source for OOM detection, disabling OOM events: open /dev/kmsg: no such file or directory
I0130 03:47:13.740891       1 manager.go:329] Starting recovery of all containers
I0130 03:47:14.131098       1 manager.go:334] Recovery completed
F0130 03:47:14.174599       1 cadvisor.go:156] Failed to start container manager: inotify_add_watch /sys/fs/cgroup/cpuacct,cpu: no such file or directory

解决办法：
# mount -o remount,rw /sys/fs/cgroup/
# ln -sf /sys/fs/cgroup/cpu,cpuacct /sys/fs/cgroup/cpuacct,cpu

二、prometheus配置
docker run -d -p 9090:9090 -v /nfs/prometheus-data/prometheus.yml:/etc/prometheus/prometheus.yml  prom/prometheus

配置文件：
global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

   #  Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

    static_configs:
      - targets: ['192.168.1.100:9090']

三、grafana展示
docker run -d -p 3000:3000 grafana/grafana
